Niese, Seattle, Wash., assigner to Zephyr Aluminum Company, Seattle, Wash., a corporation of Washington Filed Sept. 15, 1961, Ser. No. 138,459 9 Claims. (Cl. 2.0 52.2)

The present invention relates to prefabricated windows of the general type having removable sashes which slide between open and closed positions.

It is a principal object of the invention to provide such a window which may be used to replace a conventional double-hung window with a minimum of labor performed from inside the building structure and without disturbing the indoor and outdoor wall surfaces, the outside moulding, or the inside casing.

A further object is to provide a storm window with sliding sashes which can be easily removed and cleaned from indoors.

Another object is to provide a window which will not only perform the above objects, but is weather tight, pleasing in appearance, and of simple and economical construction.

Other more particular objects and advantages of the invention will, with the foregoing, appear and be understood in the course of the following description and claims, the invention consisting in the novel construction and in the adaptation and combination of parts hereinafter described and claimed.

ln the accompanying drawings:

FIGURE 1 is a top plan view in section showing a conventional double-hung window installation.

FIG. 7 is a fragmentary front elevational View partly in vertical section of a sash made in accordance with the present invention and showing part of the related border frame in phantom.

FIG. S is a side elevational View taken on line 8 3 of FG. 7.

FIG. 9 is a bottom detail view taken from the vantage indicated at 9 9 in FIG. 7; and

FIG. l is a transverse detail sectional View taken on line N ltl of FIG. 7.

Referring to the drawings of the present invention it is seen that the window of the present invention has a rectangular border frame assembly which slidably receives four removable sashes, and namely, a set of upper and lower outdoor sashes M IZ, and a set of upper and lower indoor sashes 13 14. In cross-section the border frame is generally channel shaped, the web of the channel being formed by a frame bar l and the lianges of the channel comprising pairs of outdoor and indoor track forming bars which are designated l6al7a at the head, 1Gb-17h at the two sides, and 16C-17e at the foot. Each of these track bars has an outer leg 18 which fits with a vinyl gasket 20 into the groove of respective outdoor and indoor channel portions 2 22 of the frame bar 15. The web portion between these channel portions is numbered 23 and the frame bar is completed by an indoor trim flange 24 spaced indoors of the channel portion 22 by a web extension 25. The trim flange 24 projects outwardly at 26 relative to the web extension as a support leg and this leg is complemented at the outdoor face by a leg 27 which is a continuation of the outdoor flange of the channel portion 2l. At the sill, this outdoor support leg 27 is extended as indicated at 27a and slidably receives an expander 28 of channel configuration having a sloped sill engaging base 28a.

Returning to the track forming bars, it is seen that each has an inwardly faced indoor channel continuing from its outer leg 1S and also has an outdoor channel stepped inwardly from the indoor channel as a continuation of the outdoor ange of the latter. More specilically in the case of the head track bars 16a 17a the outdoor channels are marked 39e 31a while the indoor channels are designated 32a 33a. The corresponding channels of the track bars at the sides and foot are given like identication but with B and C letter suffixes, respectively. Directing attention to FIGS. 4-5 it will be noted that the track channels 3ilb 3llb at the sides of the window have their indoor flange shortened and are narrowed at the mouth by sash guide flanges 34. Similarly, sash guide flanges 55 are provided for the side track channels 32b 33b. The indoor anges of the track channels .39@ 310 are also shortened and they have stop flanges 35 stepped below their upper edges to serve as a sash seat. Likewise, stop flanges 37 are provided on the indoor flanges of the foot track channels 32c 33c.

The four sashes lill-14 are of the same general construction, such being shown in FIGS. 7-10. At its upper corners each sash presents oppositely projecting horizontal fingers ttl-4t) which are rigid extensions of angle pieces 4l. These angle pieces tit by their legs within like head and side frame bars 42 and 43 43, respectively, which are mitered at the corners and are coined at 44 into dimples 45 in the opposite faces of the angle pieces. A second pair of angle pieces 45, minus the fingers 4b, similarly join the side bars 43 to a foot bar 47.

A pair of retractable bolts 48 48 of a general Z-shape in elevation are guided in a depending track portion 47a in the foot bar 47 to complement the fingers 4t?. These bolts are projected outwardly by compression springs 5t) l which bear against their inner ends and are housed and anchored on tabs 49 opposite the lower legs of the angle pieces 46. The free ends of these lower legs serve as stops for the jog shoulders El to retain the bolts. Depending handles 52 are provided near the inner ends of the bolts while at their outer ends the bolts have a tongue portion S3 and a key 54 which projects therefrom in the indoor direction and has a tapered end face 54a. Access to the handles 52 is aided by cutouts 55 in the bottom flange of the track portion 47a. The glass pane 56 for each sash is retained and sealed by vinyl glazing beads 57 which are forced between the edge of the pane and a beveled tongue 5S provided by the frarne bars of the sash.

The indoor llanges of the track channels 36h-30!) and B2b-3% at both sides of the window are formed with intermediate notches 62-62 and bottom notches 63 63, respectively, for receiving the keys 54 of the bolts 43 at the lower ends of the sashes 11 l2 to thereby lock the sashes. Also, as seen in FIGS. 3 and 5, the indoor flanges of the track channels 30h and 32h at one side of the window have horizontally alined slots et) and 61, respectively, such being shown on the right hand side as viewed from indoors for purposes of example. When the sashes 11-12 are in operating position in the window their lingers and bolt tongues 53 are guided in the track channels viib-ab and 32h-32h. In their closed position, illustrated in FIG. 4, the head of sash l1 nests in the channel a while the foot of sash l2 seats in the channel 32C on the related stop 37. The sashes 11-12 are locked in this closed position by action of their bolt keys S4 fitting in the respective notches 62-63- One or more additional pairs of notches 64 is provided in the indoor lianges of the side flanges 32h-32!) above the bottom notches 63 to receive the bolt keys of sash l2 so that they will hold the sash open when such is desired.

Directing attention to FIG. 5, it can be seen how the outdoor sashes lil-12 are removed for cleaning. Using sash 11 for example, and assuming that the other sashes have been removed, the sash is first lowered to bring the right hand of its fingers 4G into registration with the slot 6l). Then, after retracting the bolts LES, the sash is skewed indoors about its left hand linger to Position A from which the sash is moved both indoors and to the right so that its right hand portion enters the trough defined by the respective track forming bars 16h- Nb as indicated by Position B. The sash is then skewed to bring the left hand side through the opening defined by the indoor track bars as illustrated by Position C whereupon the sash may be moved indoors free of the window frame. lnstallation of the sash is readily performed by reversing this removal sequence.

Referring now to FG. 6, to insert the indoor sashes 13-14, and using sash 14 for example, the sash is held with the plane thereof generally horizontal with the end having the lingers 49 adjacent the window frame. FEhen the sash is cocked and moved in the outdoor direction until its fingers are in the plane of the track channels 3311 whereupon the sash is shifted laterally slightly to introduce the linger at the lower of the two side edges into the adjacent track. At this point the sash is in the full line position of FIG. 6. Dropping the raised side edge back to the horizontal as indicated by the broken line position in FIG. 6 introduces the other lingers in its related track. Then, with the bolts retracted, the bolt end of the sash is swung downwardly to the vertical about the lingers d?. as a pivot axis and the bolts are released to introduce their tongues 53 in the tracks 33h together with the lingers. The sash is removed by reversing this procedure.

Sets of notches are also provided in the indoor flanges of tie track channels Sib, 3312 to receive the bolt keys S4 of the indooor sashes lli-14 so that they can be selectively locked in closed and open positions. More particularly, notches o5 and 66 give the respective lock positions for sashes i3 and 14, respectively, and slots 67a, b and c give various open positions for the sash 14. Indirect ventilation can be provided by lowering the upper indoor pane 13 and raising the lower outdoor pane 12. If esired, a screen, indicated at 68 in FIG. 4, may be provided with the same linger and bolt arrangement as the sashes and introduced in like manner after installation of the sash 11. For this purpose a second slot 60a is provided.

It should be understood that the various slots for registering with the lingers 42 are purposely located or dimensioned such that the portion of the bolt tongues 53 outward of the related key 54 cannot pass therethrough. Likewise, the lingers 42 cannot pass through the notches for the bolt keys 54. With this arrangement there is no danger of accidentally partially removing one of the sashes while sliding it up or down.

When the sashes are in their closed positions there is some overlap therebetween as shown in FIG. 4. It is preferred that these overlapping portions ha 'e intertitting beads 69a, 69]). It is also preferred that the outdoor faces of the sash frames be provided with weather stripping to engage the outdoor flanges of the related track channels.

In FlG. l there is illustrated a conventional doubleilung Wood Window for a rough opening defined by a header, jambs E- 70, and a sloped sill 71 having a stool 75. The outdoor sash 73 of the window is held between a blind stop 72 and parting stop 76, and has its indoor Sash 7d retained by the parting stop and a trim stop 77. To replace the Window 73-74 by that of the present invention it is only necessary after cutting the sash cords to remove the trim stop 77, lift out the indoor sash 74, remove the parting stop 76, lift out the outdoor sash, insert the new window frame from indoors, screw the web 23 to the jamb at 78 (see FIG. 2), nail back the trim stop 77, and insert the sashes lil-14. The slope of the sill 71 is taken up by adjusting the expander 28 so that its base 23a bears against the sill. Each of these steps can be readily performed from inside the building structure.

`vvhen the sashes lil-ft2 are closed they function as a storm unit to conine a dead air space to the outdoors of the sashes 13--14- Yet, they can be easily opened for ventilation and readily removed from inside for cleaning. Furthermore, a screen can be simply installed and rcmoved.

it will be noted that the invention particularly lends itself to the use of extruded aluminum shapes in which case the corners of the border frame assembly may have their mitered components secured together in any suitable manner as by welding, stapling or screws.

it is beiieved that the invention will have been clearly understood from the foregoing detailed description of my novv-prelerred illustrated embodiment.
